Dual SIM Dual Standby Phones

Dual SIM dual standby feature allows you to use 2 different SIM cards in the same phone.  You can commute to different countries/cities with your roaming SIM card and destination SIM card, without the trouble to change SIM cards when you want to use the other phone number.  You can easily make and receive calls with your destination SIM card while keeping your home SIM card active.  This will help you significantly reduce your roaming charges !
